Be it known that LT1-mams Blusas, a subct the King of England, residing at Ve c "eter, Leicestershire, England have infentod certain improvements in llasteningn nserting lilachines, of which the following description, in connection with the accomdrawings, is a speciiication, like ce characters on the drmwings indicating like parts in the several figures.

This invention relates to machines for inserting fasteninos in boots and shoes and more particularly to machines capable of insertinfr a plurality oi fastenings successively and forming a plurality oit rows of such tasteni substantially simultaneously, such machines being` sometimes termed. menti-row fasteningf .inserting machines.

For purposes of illustration the invention is herein shown as embodied in a machine of the type disclosed in United. States Letters Patent No. 541,901., granted June lS, 1895, on an application of Thomas Gare, in the oi mation ot'which a plurality oft individual tasteniugs or slugs are formed from a. plurality of supplies ot continuous wire and subsef'piently .inserted simultaneously in a. boot or shoe.

be varied in accordance with the particular requirements of the shoes operated upon.

in accordance with this object of the invention, vthe illustrated machine is so con structed and arranged that corresponding` members or" the several sets ot operating instrumentalities are relatively adjustable in the line of 'feeding movement of the worl. rlhis :teature enables the machine to be adapted for different relative arrangements of corresponding fasteners of the several or less parallel to the break or line of demarcation between the shank andthe 'l`orepart o the shoe, the corresponding tastenings or' the several rows, generally speaking, being disposed inlines substantially perpcn dicular to the longitudinal median line of the shoe.

ln accordance with a further feature of the invention, the illustrated machine is so constructed and arranged that corresponding members of the several sets of @pointing instrumentalities may be relatively adjusted to cause the different rows to be inserted at varying` distances apart.

V@ther objects and features of the invention will be apparent from the tollowing detailed description when read in connection with the accompanying drawings and the novel features of the invention are set forth in the appended claims.

Although the invention is herein shown and described in its application to a slum gine; machine of the type illustrated in said Letters Patent, it is apprecia^ed that the invention as a whole or various-.features thereof may have other uses, including ap plication to slugging machines of other types. y

Referring to the drawings,

F' :'ure l is a perspective view of the head bodied therein a preferred form of the pres Y length of AWire into a wire receiving block,

Y j ed for adjustment transversely of the vline of adjustable.

relative movement between the said block and a throat member operating to sever the Wire` and dispose the severed length of Wire in alinement with a driver for the inserting operationv of. the driver. The illustrated .machine is provided with three such of instrumentalities, each comprising Wirefeeding means, a'ivire receiving and nail shearing block, a nail throat, and a driver, and the operation of the instrumentalities of each set may conveniently be effected in substantially the same manner. that the operation of the corresponding devices is effected in the machine disclosed in the Letters Patent above referred to.

In accordance with the present invention, three shear blocks, 2, 4 .and 6 are disposed transversely of the machine, the middle shear bloclr 6 being not adjustable. The out side shear blocks 2 and 4 are slidably mountfeed of the Workupon a stationary bracket 8 which projects horizontally from the machine frame, the blocks 2 and 4 being clamped in adjusted positions on the braclret S by bolts 10 and 12. The Vsaid outside blocks 2 and 4 are each provided Withtwo Wire receiving passages 14 Vand 16 respectively and the center block 6 with a single passage 14. Y f

Three fasteningreceiving throats 18, 20 and 22 each of wh ich is Yprovided with a single nail and driver passage V27 are arranged to move directly beneath the sheer blocks 2, 4 and 6, thecenter throat block -22V being not The outside throat blocks 18 and 2O have tongue and groove connections 19 with two block carriers 24 and 26 respec tively, the tongue and groove connections 19 extending in the directionof the feed l ofthe Work to enable the throat blocks 18 and 20 to be adjusted on their carriers 24 and 26 in the direction ofl the feed of the Work, as indicated by a comparison of the full and dotted lineV positions of the nail passages 27 in the outside throat blocks in rigs. 1 and 2. The said throat blocks 18 and 2O are clamped in adjusted positions y with the driver passages 27 therein in alinement with the driversby clamping bolts 2l.

The carriers 24 and 26 Vfor the outside throat blocks 18 and 20 respectively are slidably mounted upon a bracket 30 which eX- "26 are provided with threaded lugs 84 which receive the respective ends of a left and right hand screw threaded spindle 36 which is fixed against endwise movement in a lupi 38 on the center throat block carrier 40,

The milled head 41 on one end of the spindle 86 provides means for rotating thc spindle and thereby effecting a simultaneous and uniform lateral adjustment of the outside throat blocks 18 and 20.

Three drivers 45, 46 and 48 are provided to drive the astenings which are severed by movement of the passages 27 of the throats 18, 2O and 22 out of alinement with the Wire receiving passages 14 and 16 in the shear blocks 2, 4 and 6 subsequent to the feeding of the Wire through the passages 14 and 16 of the blocks k2, 4 and 6 into the passages 27. The outside drivers 45, 46 are carried respectively by driver bars 42 43 which are also disposed laterally of the machine and are carried by a. projecting bracket 50 vertically movable in guides in the head 3 and having a portion projecting downivardly to constitute a driver bar 44 for the center driver 48.

Each of the tivo outside driver bars 42 and 43 has a .tongue and slot connection 54 with the driver bar carrying bracket 50 for adjustment of the drivers 45, 46 transversely of the line of feed of the Work and into correspondence with the outsideshear blocks` 2, 4 and the outside throat blocks 18, 20. Set screws clamp the driverl bars `in their adjusted positions. Y

A uniform relative adjustment of the driver bars on the driver bracket 50 is effected simultaneously by means of a left and right Vhand screiv threaded spindle 56 Which is carried by the center driving bar 44 andA has .its ends received in threaded recesses in each of the outside driver bars 42 and 48. it set nut 58 is provided on the said spindle,

In order to allow corresponding fasten-v ings of the several roivs .to be inserted in'V j rearwardly, and for reversing this arrange ment when desired. In the preferred em bodiment of the invention, this is edected by providing each ot the outside driver bars 42, 43 with two recesses 66 for receiving the shank of the drivel', one of the recesses 60 in each driver bar being located in a hori- Zontal line passing through the shank of the center driver and the other recess beinglocated forwardly or rearwardly ot such horizontal line.

Thus with this arrangement the three drivers 45, 46, 48, may be held in their respective driver bars so as to form lines angularly disposed to the direction of feed of the work. Set screws or other appropriate devices may be provided for clamping the drivers in the recesses in which they are inserted. By reason of the two wire receiving and driver passages 14 and 16 in each of the outside shear blocks 2 and 4, the shear blocks 2 and 4 may bealined with the drivers in their dilerent angular relations without any longitudinal adjustment ot the shear blocks. l/Vhen a change in the relative adjustment of the outside drivers 45, 46 and the movable throat blocks 18 and 2O is desired in changing,- from rights to letts, the end of the wire supply is transferred in each instance in the outside shear blocks 2 and 4 to the appropriate forward or rearward passages to correspond to the wirev receiving positions of the outside movable throat pieces 18 and 2O in their adjusted positions.

Preferably and as herein shown the chine has a single awl 62 in line with the center driver inasmuch as it has been found that this arrangement permits the operator to make such changes ot' work position durinn" the Jfasteuin inserting? operation as are necessary to correct anv tendency due to initial incorrect positioning,f of the work, for example, for the rows oii wire to run in a wrongf direction relatively to the ,general contour of the work. This awl is carried by a block 64 which is mounted tor adjustment in the line ot feed ot the work upon a block 66 and is clamped in loneitudinally adiusted position uoon said block by the nut 68. The block 66 has at its forward end a laterally extendino" tongue 70 which received in the slotted lower end of the awl carrying: bracket 72. this connection providing: for a lateral adiustment oi the awl 652. .A set nut 74 clamps the block 66 in its adjusted position on the bracket 72.

The feed mechanism for the three strips of wire W comprises an inner feed roll 75 positively driven by a pawl and ratchet mechanism (not shown) and three outer rolls 76. 78, 8O mounted upon the forward ends oi" plunaers 82 which are pressed outwardly by springs not shown` located in recesses in the plunger casinfrs, all the rolls being carried by the sliding" head 3. Preterably the driven feed, roll 75 made ofsutlicient width to span the three wire supplies and the outer presser rolls 76, 78 are relatively adjustable into position to press upon the outer wires on the roll 75 in the positions in which they are located when laterally adjusted by threaded spindles 90 mounted on the ends oit plungers 82 the lateral adjustment of the outside presser rolls being commensurated with the adjustments of the drivers 45, 46 and the throat blocks 18, 20. The plungers for the presser rolls 76, 78, 8O are each provided with a milled nut 92 for relieving the pressure on the wire so that the feeding of any of the wires may be suspended.

ln the use of the machine as above described for three-row nailing, the space between the rows may be varied by adjusting the outside wire feed rolls 76, 78` the outside movable throat blocks 18, 2O and the drivers 45, 46 by rotating their respective spindles 90, 86 and 56 and by adjusting the outside shear blocks 2 and 4. In order to adapt the machine while working as a three-row slu'e'- ger on right shoes for operation upon lett shoes or vice versa', the operator changes the outside drivers 45` 46 from one set of recesses 60 to the other set ot recesses 60 in the driver bars: unclamos the outside movable throat bloclrs 18, 20 and after moving them lonnitudinallv ot the direction ot' feed of the work into correspondiner adjusted positions reclamps them to their carriers bv means of the clamping* bolts 2l z and threads the two outsidewires throueh the appropriate passages in the shear blocks 2, 4. It will be appreciated that the construction as shown lends .itself to the adiustment oi the sets oi" fastening insertinginstrumentalities to insert three rows of faetenines on a curve symmetrical with the line of feed ot the work and also convexlv thereto, as` illustrated in the drawinas, it being obvious that if the machine were to be operated with the insertingf instrumentalities adjusted in this manner the drivers would be correspondinely positioned in the recesses or holes in their support.
